Abstract
This study aimed to observe the differential expression of Annexin-A1 in esophageal squamous cell carcinoma (ESCC) and explored the effect of small interfering ribonucleic acid (RNAi)-Annexin-A1 on the biological behavior of CE81T-0 cells. An immunohistochemical approach was used to detect the expression of Annexin-A1 in 86 pairs of ESCC samples. Quantitative reverse transcription polymerase chain reaction was used to detect the expression of Annexin-A1 in CE81T-0 and CE81T-4 cells, and the expression of Annexin-A1 in CE81T-0 cells was knocked out by RNAi. A methyl-thiazolyl-tetrazolium assay was used to observe the effect of Annexin-A1 on cell proliferation, and flow cytometry was conducted to analyze its effect on cell cycles and apoptosis. A scratch assay and a Transwell chamber were used to detect changes in cell migration and invasion. From the results, compared with the Annexin-A1 expression rate of 59.3% in para-carcinoma tissues, the expression of Annexin-A1 in cancer was reduced to only 32.6% in ESCC cells. Annexin-A1 was strongly expressed in highly differentiated ESCC cells without lymphatic metastasis and highly expressed in the CE81T-0 cell group with low metastasis. Annexin-A1 gene silencing promoted cell proliferation and inhibited apoptosis, blocked cells in the S-phase, and increased cell migration, leading to an increase in the number of invaded cells. Above all, Annexin-A1 could reflect the differentiation degree and lymph node metastasis of ESCC cells to some extent and was involved in the invasion, metastasis, proliferation, and other biological behaviors of ESCC cells, indicating an experimental basis for Annexin-A1 as a molecular marker in the early diagnosis of ESCC and the prediction of cell metastasis, invasion, and differentiation degree.

Abstract
Objective: To analyze the bronchoscopic manifestations and interventional treatment of pulmonary mucormycosis. Methods: Clinical data of patients with pulmonary mucormycosis undergoing bronchoscopy and interventional therapy in 4 tertiary general hospitals in China from May 2006 to May 2022 were retrospectively analyzed and the literature on the subject were reviewed. Results: The data of 10 patients with pathologically diagnosed pulmonary mucormycosis undergoing bronchoscopy and interventional therapy were collected, including 8 males and 2 females. The patients' age ranged from 21 to 72 (44±15) years. The underlying diseases included 6 cases of diabetes ketoacidosis, 3 cases of leukemia, 1 case after operation of lung cancer. Bronchoscopy showed that white viscous necrotic matters grew along the airway and blocked the airway in 9 cases, accompanied by airway bleeding in 3 cases, bloody secretion blocked the airway in 1 case, and bronchopulmonary cavity fistula in 2 cases. The biopsy histopathology of white necrotic matters showed that many mucor filaments were tangled together which were named mucormycelium. Among the 10 patients, 9 were treated with systemic drugs, including intravenous application of amphotericin B deoxycholate in 5 cases, intravenous application of amphotericin B liposome in 4 cases, oral posaconazole in 6 cases and intravenous injection in 1 case. Local drug therapy included aerosol inhalation of amphotericin B deoxycholate in 8 cases and local perfusion under bronchoscope in 5 cases. Bronchoscopic interventional therapy was used to remove mucormycelium in the bronchus, including cryotherapy in 8 cases, biopsy forceps in 7 cases, snare treatment in 2 cases and foreign body forceps in 2 cases. All 10 patients were clinical cured and with no death. Conclusions: Pulmonary mucormycosis is more common in immunocompromised hosts. Bronchoscopy often showed mucormycelium blocking the airway. Systemic and local drug therapy combined with bronchoscopic interventional therapy can achieve good clinical efficacy.

Abstract
Objective: To investigate the clinicopathological, molecular genetic, immunohistochemical and prognostic features of spinal solitary fibrous tumor (SFT). Methods: The clinical data of 12 cases of spinal SFT in Beijing Tsinghua Changgung Hospital, Affiliated to Tsinghua University, diagnosed from January 2015 to December 2021 were collected and reclassified. The clinical data, histopathology, immunohistochemistry and molecular genetics were analyzed. Follow-up and related literature reviews were conducted. Results: Among the 12 patients, there were 5 males and 7 females; the age ranged from 31 to 73 years, with a median age of 50.5 years. All 12 cases were primary tumors, including 4 cases diagnosed at the first time and 8 recurrent cases. Among the 12 cases, 8 were WHO grade 1, 3 were WHO grade 2, and 1 was WHO grade 3. Microscopically, the spinal SFT appeared as a spindle cell tumor, the stroma was rich in many thin-walled blood vessels with various histological features such as cell morphology and necrosis according to the different tumor grade. All (12/12) of the cases expressed vimentin and STAT6 (diffuse and strong nuclear stain), 11 cases (11/12) expressed both CD34 and bcl-2, and 7 cases (7/12) expressed CD99. Next-generation sequencing showed that 12 (12/12) of the patients had NAB2-STAT6 gene fusion. The 12 patients were followed up for 6 to 80 months. There were no recurrences or metastases in the 4 first cases after operation. Among the 8 recurrent cases, 2 of the patients relapsed and 2 died. Conclusions: Spinal SFT is rare and has a high recurrence tendency. Many aspects need to be considered in the diagnosis process. STAT6 is a relatively specific marker for the diagnosis of this tumor. Complete surgical resection is the preferred treatment while postoperative radiotherapy is recommended to reduce tumor recurrence.

Abstract
The present study aimed to establish esophageal squamous carcinoma cell (ESCC) sublines with different invasive and metastatic potentials. Gene microarrays were used for differential gene screening with the establishment of ESCC invasive metastatic gene expression profiles. Some differential gene expressions were validated. Parent line Eca109-T0 was screened in a Transwell chamber to establish Eca109-T4 with high invasion and metastasis. The migrative and proliferative capacities of ESCCs were compared. The Eca109-T0 and Eca109-T4 cell lines were taken as the research objects and were hybridized with gene chips to obtain cell sublines for the screening of differential genes of ESCCs with varying invasive and metastatic potentials. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) clustering analyses were conducted. Some differential genes (HSP90AA1, ANXA1, YWHAB, CXCR7, SDC2, and TNFRSF10D messenger ribonucleic acid) were validated by qualitative real-time polymerase chain reaction and Western blot analysis. As a result, some Eca109-T4 ESCC sublines with high invasive and metastatic potential were screened in a Transwell chamber. The gene chip analysis screened out 326 differential genes, of which 123 were upregulated and 203 were downregulated by Eca109-T4. The GO cluster analysis indicated that the genes were in the cytoplasm, nucleus, and cytosol. The molecular functions of these genes involved the binding of proteins and metal ions and participation in biological processes, including cell signal transduction, transcription, and apoptosis. The KEGG clustering showed that these genes were mainly involved in signaling pathways, such as actin cytoskeleton regulation, the mitogen-activated protein kinase pathway, and the cancer pathway. The validation results were basically consistent with the gene microarray screening results. In Eca109-T4 and CE81T-4, HSP90AA1, YWHAB, and CXCR7 were highly expressed, while the expression of ANXA1 was low. In conclusion esophageal squamous carcinoma cell models with different invasive and metastatic potentials were established. The establishment of differential gene expression profiles for invasion and metastasis together with a bioinformatics analysis provided rich information for studies related to ESCC invasion and metastasis. HSP90α, 14-3-3β, and CXCR7 were highly expressed in ESCCs with high invasion and metastasis, while Annexin A1 was highly expressed in ESCCs with low metastasis.

Abstract
OBJECTIVE To investigate the effects of epigallocatechin-3-gallate (EGCG) on proliferation and apoptosis of human gastric cancer SGC7901 cells under a hypoxic state. MATERIALS AND METHODS Human gastric cancer SGC7901 cells were sub-cultured, and the cobalt chloride (CoCl2) hypoxia model was established. The blank control group (normoxia group), hypoxia control group (hypoxia group) and hypoxia + different concentrations of EGCG subgroups (20, 40, 60, 80, 100 μg/mL EGCG) were set up. Cell viability was detected via methyl thiazolyl tetrazolium (MTT) assay, apoptosis was detected via flow cytometry, and expressions of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) were detected via reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting. RESULTS Relatively low concentrations of EGCG (20-80 μg/mL) presented no significant inhibiting effect on SGC7901 cell growth within a short time (24 h) (p>0.05). The increasing concentration of EGCG inhibited cell proliferation under a hypoxia state (p<0.05). EGCG induced apoptosis in a dose-dependent manner under hypoxia (p<0.05). EGCG could significantly impede expressions of HIF-1α and VEGF proteins (p<0.05), and down-regulate the level of VEGF mRNA (p<0.05), but it showed no significant effect on the HIF-1α mRNA expression (p>0.05). CONCLUSIONS EGCG inhibited cell proliferation under hypoxia via the downregulation of HIF-1α and its downstream target gene VEGF levels, providing a theoretical basis for the early diagnosis and treatment of gastric cancer in clinic.

Abstract
Objective:To investigate the value of laryngoscopy and MRI in diagnosis and management of pharyngolaryngeal venous malformations(VMs), and to provide reliable evidences for clinical application. Method:The clinical data of 73 patients with pharyngolaryngeal VMs was analyzed retrospectively. Laryngoscopy and MRI were detected before treatment. The involved anatomic sites and the volume of VMs were calculated by Mimics version 20.0. Result:No significant difference was found in the detection rate of VMs between laryngoscopy and MRI(P>0.05). The most common sites involved in pharyngolaryngeal VMs were the tongue base(37.0%), followed by epiglottis(35.6%) and pyriform sinus(32.9%). The volume of pharyngolaryngeal VMs ranged from 0.75 cm³to 76.33 cm³, with an average volume of (17.43±6.28) cm³. Conclusion:Laryngoscopy and MRI have their own advantages in diagnosing of pharyngolaryngeal VMs. Thus a combination which provides more information to formulate reasonable treatment plan has great diagnosing value. When treating with facial and cervical VMs, routine laryngoscopy is recommended to screen and to evaluate the laryngopharyngeal involvement.

Abstract
Objective: To explore the differences in epidemiology and clinical features of Guillain- Barré syndrome (GBS) between rural and urban areas of southern China. Methods: The clinical data of 759 hospitalized GBS patients from 31 hospitals of 13 provinces/cities in southern China, between January 1st, 2013 and September 30th, 2016, were collected and analyzed retrospectively. Results: The risk of GBS was higher for males than females in rural and urban areas and the median age was 49 and 48 years, respectively. Seasonal clustering in winter and spring was noted in both rural and urban areas, and the seasonal trend was more markedly in rural areas, but the differences showed no statistical significance. There were 70.37% of patients in rural areas and 73.69% in urban areas who had antecedent respiratory infection. The median time from onset to nadir was 7 days, and Hughes Disability Scale at admission, nadir and discharge were (2.95±1.10 vs 2.84±1.15), (3.25±1.11 vs 3.14±1.21), (2.02±1.24 vs 2.00±1.31) in rural and urban areas respectively. Albuminocytologic dissociation was present in 84.34% of patients in rural areas and 84.62% of cases in urban areas. There were 8.65% and 10.94% of cases in rural and urban areas who required mechanical ventilation during hospitalization, respectively. Demyelinating GBS accounted for 53.29% and 48.77%, respectively, in patients with findings of nerve conduction studies available in rural and urban areas. Conclusions: GBS in rural areas of southern China showed male predominance and a peak of spring and winter occurrence, with respiratory infection as the predominated preceding events and demyelinating GBS being main clinical subtype. Winter and spring showed a higher incidence of GBS in rural and urban areas. There were no significant differences of sex, age, preceding events, season trend, progression of disease, clinical subtypes and cerebrospinal fluid investigations in GBS patients between rural and urban areas.

Abstract
Objectives The length of the tourniquet time during total knee arthroplasty (TKA) is related to the incidence of post-operative deep vein thrombosis (DVT). Our aim in this study was to investigate the effect of the early release of the tourniquet on the incidence of DVT in patients undergoing TKA. Methods A total of 200 patients who underwent TKA between November 2015 and November 2016 were prospectively enrolled. The tourniquet was inflated before surgery and released immediately after the introduction of the components (early release group). This group was compared with a retrospective cohort of 200 primary TKAs, in which the tourniquet was released after the dressings had been applied (late release group). The presence of a DVT was detected using bilateral lower limb ultrasonography. Peri-operative clinical and follow-up data were collected for analysis. Results The incidence of DVT in the early release group (9 of 196, 4.6%) was significantly lower compared with the late release group (24 of 200, 12%; odds ratio (OR) 0.35, 95% confidence interval (CI) 0.16 to 0.78, p = 0.008). The incidence of proximal DVT in the early release group (1 of 196 (0.5%)) was significantly lower than in the late release group (8 of 196, 4%; OR 0.12, 95% CI 0.02 to 0.99, p = 0.020). Although the mean intra-operative blood loss was higher in the early release group, the mean post-operative drainage, total blood loss, transfusion requirements and complications were not significantly different in the two groups. Conclusion In patients who undergo TKA, releasing the tourniquet early is associated with a decreased incidence of DVT, without increasing the rate of complications.

Abstract
This study was conducted to evaluate the influence of back-fat thickness (BF), at mating of sows, on the maternal and newborn circulating lipids, expression of placental fatty acids (FA) transporters and lipid accumulation in placenta. Full-term placentas were obtained by vaginal delivery from BFI (9-14 mm; n = 37), BFII (15-19 mm; n = 43) and BFIII (20-27 mm; n = 38) sows according to BF at mating, and frozen placental sections were analysed for fat accumulation. Blood samples were collected from the sows of day 105 pregnancy and from cord blood at delivery. mRNA and protein expression levels were evaluated with real-time RT-PCR and Western blotting. Our results demonstrated that BFII females had significantly increased litter weight and placental efficiency, decreased maternal triglyceride (TG) and non-esterified fatty acids (NEFA) levels, decreased maternal IL-6, TNFα and leptin levels compared to BFIII females (p < .05). BFIII sows were associated with significantly decreased newborn TG levels, increased newborn glucose, IL-6 and TNFα levels compared to BFI or BFII sows (p < .05). BFI and BFII females had significantly decreased placental TG, NEFA and cholesterol (CHOL) contents compared to BFIII females (p < .05). Moreover, decreased CD36, FATP1, FABP4, and FABP1 mRNA and protein and FATP4 protein expression, and increased LPL activity were also observed in BFIII group compared with BFII group (p < .05). PPARγ mRNA and protein and lipogenic genes such as SREBP-1c, ACSL1, ACCα, FAS and SCD mRNA expression were downregulated or upregulated, respectively, in the placentas of BFIII sows compared to BFI or BFII sows (p < .05). Overall, this study demonstrated that there is no advantage, in terms of litter live size, litter weight and placental FA transport and metabolism, in performing the mating of sows with BF>19 mm.

Abstract
OBJECTIVE Cullin 4B (CUL4B) is a component of the Cullin 4B-Ring E3 ligase complex (CRL4B) that plays a role in proteolysis and is implicated in tumorigenesis. However, little is known about CUL4B function in human brain tumors, including glioma. MATERIALS AND METHODS Here, to investigate the involvement of CUL4B in glioma tumorigenesis, endogenous CUL4B expression was depleted in glioblastoma cell lines U87 and U251 by RNA interference (RNAi). RESULTS Knockdown of CUL4B via shRNA-delivering lentiviruses significantly decreased cell proliferation and colony formation, causing G1 phase cell cycle arrest in both cell lines via down-regulation of cyclin D1 and up-regulation of p16. While increasing the expression of the tumor suppressor PTEN, CUL4B knockdown alleviated in vivo tumorigenesis in glioma xenograft nude mice and impeded cell migration via suppression of MMP-9. CONCLUSIONS Therefore, knockdown of CUL4B is likely to provide a novel alternative for targeted therapy of glioma deserving further investigation.

Abstract
We have previously shown that MEF (myeloid ELF1-like factor, also known as ELF4) functions as a transcriptional activator of the interleukin (IL)-8, perforin, granulocyte macrophage-colony stimulating factor (GM-CSF) and IL-3 genes in hematopoietic cells. MEF is also expressed in non-hematopoietic tissues including certain ovarian cancer cells. To define the function of MEF in these cells, we examined primary human ovarian epithelial tumors and found that MEF is expressed in a significant proportion of ovarian carcinomas, and in the CAOV3 and SKOV3 ovarian cancer cell lines, but not in normal ovarian surface epithelium. Manipulating MEF levels in these cell lines altered their behavior; reducing MEF levels, using short hairpin RNA expressing vectors, significantly inhibited the proliferation of SKOV3 and CAOV3 cells in culture, and impaired the anchorage-independent growth of CAOV3 cells. Overexpression of MEF in SKOV3 cells (via retroviral transduction) significantly increased their growth rate, enhanced colony formation in soft agar and promoted tumor formation in nude mice. The oncogenic activity of MEF was further shown by the ability of MEF to transform NIH3T3 cells, and induce their tumor formation in nude mice. MEF is an important regulator of the tumorigenic properties of ovarian cancer cells and could be used a therapeutic target in ovarian cancer.

Abstract
The effects of chrysene and the ozonated byproducts on in vitro gap junctional intercellular communication (GJIC) were evaluated using the scrape loading/dye transfer (SL/DT) technique. A 1 mM solution of chrysene was ozonated at dosages of 1.75, 3, 4.25, and 5 mol O3/mol chrysene (Chr). The early ozonation mixture, 1.75 mol O3/mol Chr, exhibited greater inhibition to GJIC than chrysene and irreversible damage to cells leading to cell death. To determine the compounds potentially responsible for the increase in toxicity, the byproducts formed upon treatment with 1.44 mol O3/mol Chr were separated into 14 fractions using RP-HPLC. The major compounds identified in the fractions were 2-(2'-formyl) phenyl-1-naphthaldehyde, 2-(2'formyl) phenyl-1-naphthoic acid, and 2-2-carboxyphenyl-1-naphthoic acid. 2-(2'-Formyl) phenyl-1-naphthaldehyde was determined to be the compound causing GJIC inhibition in sample fractions and byproduct mixtures.

Abstract
AIM To study the reversal effects of droloxifene (DRO) on multidrug resistance (MDR) in K562 cell line resistant to adriamycin (ADR). METHODS K562 cell line resistant to ADR (K562/A02) and K562 cell line sensitive to ADR (K562) were treated with DRO. Using MTT assay, chemosensitivity to ADR in DRO-treated K562 cell lines was studied. Before and after the treatment with DRO 10 micromol/L, MDR1 and GSTpi gene expression were assayed by reverse transcription-polymerase chain reaction and immunocytochemistry assay. Flow cytometry was used to determine intracellular ADR concentration. RESULTS DRO significantly reversed MDR in K562/A02 (P < 0.01). After treatment of DRO 20, 10, and 5 micromol/L, the chemosensitivity to ADR was increased to 14, 13, and 4 folds, respectively. The reversal activity of DRO was similar to that of verapamil (VRP). After treated with DRO 10 micromol/L, both MDR1 and GSTpi mRNA expression began to decline on the 2nd day, and significantly decreased on the 5th day (P<0.01). The changes in P-gp and GSTpi protein expression were similar to that of their mRNA expression. Two hours after treatment of DRO 20, 10, and 5 micromol/L, intracellular ADR concentration in K562/A02 was increased to 2.9, 2.3, and 1.5 folds, respectively. However, DRO did not markedly increase ADR accumulation in K562. CONCLUSION DRO had strong reversal effect on MDR in K562/A02, which was comparable to that of VRP, but the reversal effect was via different pathways.

Abstract
beta-endorphin-like immunoreactivity (beta-ELI) was measured in cerebrospinal fluid (CSF) of 36 acute head-injured patients and 12 patients without head injury as controls. The mean level of beta-ELI in CSF of controls, mild cerebral contusions, and severe cerebral contusion patients were 51.9 +/- 5.6 pg/ml, 110.5 +/- 14.5 pg/ml, and 173.8 +/- 20.1 pg/ml respectively, with significant difference between them. The results also showed that beta-ELI may reflect the prognosis of acute head-injured patients.
